CORS issues when deployed with domain name

[DenisIvanovIvanov]

I'm using the template to create small web app for my wife.

I've finally deployed it with domain name and SSL, but login redirect doesn't work because of CORS. The error is
CORS request made for path: /sockjs-node/701/xvyuio0h/xhr from origin: https://domainname.com but was ignored because path was not for an allowed IdentityServer CORS endpoint"

I've tried enabling all cors as suggested

services.AddSingleton<ICorsPolicyService>((container) => {
     var logger = container.GetRequiredService<ILogger<DefaultCorsPolicyService>>();
     return new DefaultCorsPolicyService(logger)
     {
          AllowAll = true
      };
});

services.AddCors(options =>
{
     options.AddPolicy(name: "_myAllowSpecificOrigins",
               builder =>
               {
                    builder.AllowAnyHeader()
                                  .AllowAnyMethod()
                                  .AllowAnyOrigin();
               });
      });

And using it

app.UseRouting();
app.UseCors("_myAllowSpecificOrigins");

but it still doesn't work. Can someone help on that?
